Don't see it happening at E3. Why cut the price to boost sales across the summer, when sales are going to be modest regardless.
Gamescom in September is more likely. They have to cut the price this year if they don't want to see sales lower than 2014, so a $50, or $70 if they can manage it, sometime around September or October, would be the best bet I think.
